 Since the Birdhouse Factory people also like internet technology, they combined these interests and run their own webshop where you can buy birdhouses online, and their own mail server. The Factory has some IPv4 space allocated from an ISP, where they run their servers, and where they have a NAT router in front of their office network, which uses RFC1918 IPv4 network ranges.
